P*TIME: Highly Scalable OLTP DBMS for Managing Update-Intensive Stream Workload

Summary: Memory-centric, lightweight OLTP RDBMS designed for update-intensive stream workloads, delivering orders-of-magnitude scalability on commodity SMP hardware. Engine-level micro-parallelism with differential logging and latch-free optimistic index traversal enables high update and search performance, showcased as the stock-market DB at a major online brokerage.
